Iterate Faster,
Ship Better Agents
Collaborate With Your Team
Gather expert feedback on agent performance and iterate on prompts with your team. Share traces so anyone can understand user behavior, debug issues, or assess response quality.
Start Building, Then Invite Your Team
Studio runs on localhost. When it's time, share it behind a URL — your team gets the same workspace.
Authentication
Lock down Studio with role-based access. Define who can view, edit, and execute.
Invite Domain Experts
Invite your team to traces, build datasets, run experiments, and refine prompts, even if they don't have access to the source code.Own your agent loop
Studio gives your team one place to learn from real usage, iterate faster, and improve every release.
Iterate Quickly
Test your agents in Studio. Switch models, tweak settings, and try different inputs.
Scorers
Score outputs with LLM-as-Judge or code. Run online evals in production or score any historical trace retroactively.
Datasets and Experiments
Define what good looks like, then measure against it. Build regression sets from production traces and run experiments after every change.Start building with a free account, or explore our pricing for more
